Groupon leads the parade of e-commerce stock losers

Groupon Inc. suffered a 28% decrease in its stock price last week after reporting disappointing Q3 financial results. That was the largest percentage drop in last week’s Internet Retailer Online Retail Index, in a week that brought more losses than gains.

While Groupon enjoyed a 32% increase in revenue in Q3, the daily deal provider’s sales gain fell short of analyst expectations. The weekly Online Retail Index, which tracks the stocks of online retailers and e-commerce technology providers, as a whole decreased by 4.5% last week. That put the e-commerce index behind the broader stock market, as the Dow Jones Industrial Average decreased by 2.12% and the Standard & Poor’s 500 Index increased by 2.43% in value last week.

Of the 25 stocks in the Online Retail Index, nine had increases, while the stocks of 16 companies decreased in value.

Following are the best-performing stocks last week in the Online Retail Index and the percentage gain in stock price for each:

• Bidz.com, 16.3%

• Digital River, 2.2%

• Netflix, 1.3%

• Systemax, 1.0%

• Overstock.com, 0.7%
